Astro 7N PSU Exam 1
Newton's 1st Law
An object at rest remains at rest except acted upon through a pressure
Newton's second Law
F=ma
Newton's 3rd Law
For every motion, there is an same and opposite response
Strength of Gravity
g=M/(R^2)
Force of Gravity
F=(M1M2/(D^2))
Sun's Movement
East to West
Due to Earth's rotation
Phase Order of the Moon
New --> Waxing Crescent --> First Quarter --> Waking Gibbous --> Full --> Waning Gibbous -->
Third Quarter --> Waning Crescent --> New
Full Moon
Sun--Earth--Moon
New Moon
Sun--Moon--Earth
Constellation
, Large defined vicinity in the sky
There are 88
Forms of Light
Gamma, X-Ray, UV, Visible, Infrared, Microwave, Radio
Bluer Color
Short wavelength
High frequency
Redder Color
Long wavelength
Low frequency
Continuum Spectrum
Light in any respect wavelengths
Absorption Spectrum
Shows dark lines within the spectrum at positive wavelengths
Produced by using a gas cloud in the front of a mild source
Absorption Line
Dark strains in the spectrum at sure wavelengths
Produced whilst photons are absorbed by using electrons and the electrons circulate from a
decrease to better power degree
Emission Line
Bright traces at particular wavelengths
Due to emission of photons from atoms
Produced when electrons jump from better to lower strength tiers
Light-Gathering Power
Important first-rate of a telescope
Amount of light a telescope can collect
